## Questions & Answers

**Q: does it fit in 10 mm bolts? thanks**
A: NO, you would need to get one for 10mm bolts.  This one will NOT work.

**Q: Doe anyone know if the 1/2" socket is "sloppy" (oversize: 0.512" ) enough to fit a 13mm nut?**
A: Most 12 point wrenches have some "play" in them but I would recommend getting the 13mm torque adapter instead.

**Q: i already have the 1/2" and 3/8" size of this torque adapter. How can I purchase the 1/4" size? is there a part#?**
A: I don't think anyone makes a 3/8 drive 1/4" torque adapter. Best bet is a 1/4" wrench because the torque on a fastener that size will be minimal. Light pressure on the wrench will do the trick
